I have been to both Mississippi and Portugal.
I've had a great time eating ribs in Tupelo and hiking in Peneda-Geres National Park near Porto.
Lisbon and Porto is a pretty city but Portugal as a whole has historically been an underdeveloped laggard in Europe due to political mismanagement (just like Mississippi) and only developed thanks to massive cash+infrastructure transfers by the EU, just like how Mississippi and other southern states were transformed via FDR's New Deal and LBJ's Great Society.
